SPECIFICATION forming part of Letters Fatent No. 416,481, dated December 3, 1889.

Application filed November 28, 1888. $erial No. 292,123. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN C. MILAM, a citizen of the United States, residing at Frankfort, county of Franklin, State of Kentucky, have invented a certain new and useful Improvement in Window-Frame Sash, of which the following is a full, clear, and exact specification.

My invention relates to window-sashes; and it consists of novel means for detachably securing the sashes within the casing and for preventing rattling of the sash.

In the drawings, Figure 1 is a face view of a Window containing my invention. Fig. 2 is a front view of one of the sashes with its confining-strip shown in position to be removed. Fig. 3 is a cross-section on the line 3 3 of Fig. 1. Fig. 4 is an edge view, enlarged, of a portion of one of the confining-strips. Fig. 5 is a perspective View of the confining-strip and its locking-button.

The casing A of the window is of usual construction, except that the strips a, which are ordinarily employed to form the guideways for the sashes, are dispensed with altogether, or, preferably, are used on one side only, as shown in the drawings.

In place of the strips a, I employ detachable confining-strips B, carried by the sashes O, and arranged to have their outer edges run in grooves 12, formed in the casing, which grooves may be those ordinarily formed in the casing for the reception of the strips a, or narrower grooves specially formed to receive the strip B.

The strips B are by preference of a length about equal to the height of the sashes to which they are secured,and project sufficiently beyond the edges thereof to properly engage with the grooves b. In order that they may be readily detached from and secured to the sashes, each strip is by preference provided with two slots-a short longitudinal slot 1,near one end of the strip, and a transverse slot 2, extending from the outer edge of the strip, near the other end. These slots permit the strip to slide upon the pins or screws d e, carried by the sash, and which serve to confine the strips in place. When it is desired to remove the strip, it is first turned into the fullline position, (illustrated in Fig. 2,) upon the pin d as a fulcrum, this being permitted by ated manner in Fig. 4.

the slot 2. Having by this movement cleared the pin 6, the strip is slid into the dotted-line position, whenit maybe removed, leaving the sash free to be moved into or out of the easing, as will be readily understood.

WVhile the strip B would be held in place by the pins 01 and e, I prefer to employ a button F for locking the strip. The button is fulcrumed upon the pin f, and is arranged that it may turn over the inner edge of the strip, which is by preference beveled at '3, the under face of the end of the button being inclined to fit the bevel 3. In order that the button shall not pass beyond the locking position, I provide a stop to limit its movements, which stop in this instance consists of a shoulder t at the end of the bevel 3, 'against which the button abuts. The button has a portion of its front edge cut away, forming a shoulder 5, which, when the button is in the locking position, lies against the inner edge of the strip, just below the shoulder 4, and receives the thrust of the strip should an attempt be made to move it without first turning -back the button.

I utilize the strip 13 as an anti-rattling de-- vice, for which purpose I split one end of the strip by sawing or otherwise and insert in the lower part of the kerf or cut a block or wedge G, which forces apart the portions 6 of the strips, as represented in a somewhat exagger- These parts 6 of the strip form spring leaves, which, bearing against the sides of the slots I), prevent rattling of the sash in the frame. Both ends of the strip may be thus made to serve as antirattlers, although I consider it suflicient to so utilize but one end, the portion of the strip between the slot 1 and the outer edge only being split.

The above-described invention is simple in construction and permits the sashes to be easily taken from the casing for cleaning or other purposes Without removing any of the permanent parts of the Window. The antirattling device is also so simple andis capable of being adjusted to fit a groove of any width by employing a larger or smaller block or wedge.

It will be understood that in the details of arrangement there may be changes without departing from the spirit of my invention, as

by reversing the positions of the slots 1 and 22a but all such changesl do not consider it necessary to specify, since they do not change the principle of my invention.

Without limiting myself to the precise construction and arrangement of parts shown, I claim 1. The combination, with a sash and its casing provided with a groove, of pins carried by the sash, the detachable conliningstrip adapt-ed to slide in the said groove, having a longitudinal and a transverse slot arranged to permit the strip to slide upon the pin and into the said groove, substantially as set forth.

2. The combination, with a sash and its casing having a groove, of the pins carried by the sash, and the detachable confining-strip having the longitudinal slot at one end and the transverse slot extending from the outer edge of the strip, the said slots permitting the slat to slide upon the said pins, by which it is secured to the sash, substantially set forth.

3. The combination, with the sash and its casing, of the pins upon the sash, a confiningstrip detachably resting on the said pins and engaging with a groove in the casing, and a locking-button for the said strips, substantially as set forth.

4. The combination, with the sash and its casing, of the detachable confining-strip 13, having the slmulder 4, and the turning button 1*, having the shoulder 5, which looks against the shoulder 4, thereby stopping the button in position to hold the strip in place, substantially as set forth.

5. The combination,with a sash, of an antirattling device consisting of a eonfining-strip secured to the sash and moving in a groove in the casing, having its ends split and expanded to form spring-blades, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence oi. two subscribing witnesses.
